Arsenal have won the race to sign Saint-Ettiene defender William Saliba, who rejected late interest from Tottenham to agree a £27 million move to the Emirates.

The 18-year-old Frenchman will become Arsenal’s second signing of the summer following the arrival of another teenager Gabriel Martinelli and Football London claims the Gunners are confident of making Celtic defender Kieran Tierney their third capture.

Arsenal are reportedly confident they will agree a deal of around £25 million with Celtic for Tierney.

The Gunners have had two bids rejected by the Bhoys, who had been hoping to get around £30m for the Scotland international.

However, Tierney has made it clear that he would be keen on a move to the Emirates and Celtic are resigned to losing the 22-year-old.

Once Tierney’s move is complete, the Gunners will focus on a loan deal for Real Madrid ace Dani Ceballos.

Deals for Tierney and Saliba will have used up the majority of Unai Emery’s transfer budget but the likes of Carl Jenkinson, Mohamed Elneny and Calum Chambers could be sold to raise extra funds.

The club were keen on signing Crystal Palace forward Wilfried Zaha and offered Jenkinson, Elneny and Chambers in exchange for the Ivorian, as well as £40m. However, the deal was rejected out of hand by the Eagles, who value Zaha at closer to £90m.
